Rock To The Rhythm Set 解禁条件：Lv20 BOSS分岐しきい値：10 No. 曲名 難易度 備考 1 Forever 6 - 2 Brandnew Days 7 - 3 Keys to the World 7 - 4 You should get over me 7 - 5 Dual Strikers 7 - 6 Feel Ma Beat 7 - BOSS1 Oblivion -Rockin night style- 9 - BOSS2 Fallen Angel ? EXTRA このコースついての情報はコメント欄へ。 BOSS2が飛び抜けて難しい -- 名無しさん (2013-04-26 01 32 44) ロック曲がそろったディスクセット。セレクト曲はそこまで難しくないが、ドラムやギターの音を打つことが多いため、ロック調の曲をあまりプレイしてない人は練習必須。５が少し難しい。ここからボス曲の難易度が急激に上昇する。ボス１でも難易度９で、セレクトを突破できるぐらいの実力じゃゲームオーバーになる。といってボス２は通常プレイできないEXTRA譜面であり、これも簡単にはクリアできない。人にもよるがごり押しするならボス２のほうが楽。 -- 名無しさん (2013-08-05 23 17 06) ついにLV9が登場。BOSS1はPOPとは別物でとにかく複雑な譜面なので落ちて覚えるしかない、慣れれば9妥当になるはず。またBOSS2はLv20の時点だとEXTRA譜面でしか遊べないので曲ぐらいは聴いておいた方がいいかもしれない。突破難易度はどちらもさほど変わらないと思われる。 -- 名無しさん (2013-10-01 16 23 46) 名前 コメント
